Nice quality! Very easy to install. Fit back into place perfectly. Didn't notice a big change in sound. Maybe a little deeper tone, but nice. Glad I made the purchase.

This system is excellent! I installed this system on my LMM Duramax after I had some issues with my Banks Monster exhaust system. System fit perfect and my inital test the mileage and horsepower gains were above both the Banks and the stock system. I am gonna play with the programmer and see what kind of results I can get. I am impressed by this system and it is going to stay on my truck! I highly recommend this system to anyone!
